Fig. 7 is a perspective view showing another embodiment of the presentinvention.

Referring to thedrawings, the barricade is shOwnconsisting of a standard10, supporting a sign frame 11 comprised of a pair of substantiallyidentical vertical side members'12 (only one of which is shown in thefigure), a lower horizontal frame member 13 and an upper horizontalframe member 14. The members 12, 13 and 14 may be any suitable form ofshafting, such as conventional water pipe which is readily obtainableanywhere in the country. At its upper end, each vertical member or shaft12 is secured to the respective ends of the upper shaft or pipe 14 by aconventional pipe elbow 16 into which the pipes 14 and 12 are threaded.If desired, the joint at 16 may be prefabricated by being welded. Withinthe space outlined by frame 11 is secureda flat sign 17, which may bemade of. sheet metal or other suitable sheetlike mateiral. The sign 17has a pair of tubular sleeves 18; formed at each side thereof, whichencircle the respective vertical shafts 12 to secure the sign 17 inplace in the frame 11.

At their respective lower ends, the vertical shafts '12 are secured tothe respective ends of the lower horizontal shaft 13 by'a special joint19 constituting an important feature of the present invention. As seenin detail in Fig. 2, the joint. 19 comprises a body having threeangularl'y spaced socketportions 21, 22, and 23, the axes of which aredisposed generally co-planar in a vertical plane. Substantially at thecommon intersection of these three socket axes is the axis of anothersocket, i. e., a horizontal socket 24. The socket 21 extends directlyupward and receives the vertical shaft 12 constituting a portion of theframe 11. The socket 24 is at right angles to 'the socket 21 andreceives the horizontal shaft 13 of the frame 11.. Thus the socket 19serves (among other functions) the purpose of forming one of the cornerjoints of the frame 11.

The sockets 22 and 23 are directed' generally downward' but divergesymmetrically away from the vertical axis of the upper socket 21, so asto receive shaft members 26 and 27, respectively, constituting two ofthe legs of .the standard supporting sign frame 11. It will beunderstood that the other end of the sign frame 11 is similarly equippedwith a socket 19 and with legs 26 and 27. At their bottom ends, the legs26 and 27 are provided with horizontal extensions 28, whichserve to givethe barricade greater stability particularly ainst high winds blowingagainst the face of the sign 17, which tend to tip the barricade over.

Directly opposite the socket 24, the joint 19 is provided with asubstantially fiat, vertical face 29. Inthe face 29 are threesubstantially horizontal tapped or threaded bores 31, 32 and 33communicating with the interiors of the respective sockets 21, 22 and23. Threaded in the bore 31 is a set screw 34 which secures the shaft orpipe 12 in the socket 21. To this end, the pipe 12 is-provided with anaperture'36 through which the set screw 34 passes, the inner end of theset screw 34 abutting against the inside opposite wall of the pipe 12,which is not apertured. In order to permit the set screw 34 toberecessed in the face 29, the set screw 34- has a socket type head asillustrated at 37.

The legs 26 and 27 are similarly held in place in their respectivesockets 22 and 23 by similar set screws 36 threadedly secured in therespective bores 32 and 33, as. shown in Fig. 5.. Likewise, thehorizontal pipe 13 is secured in its socket 24 by a set screw 39threaded in a tapped bore 41 formed'in the upper wall of the socket 24.

In order to maintain the legs 26 and 27 in proper position :duringassembling of the barricade so as to prevent these legs from blockingfull entranceof the shaft 13,

stop bosses 42 are formed on the inside of the joint 19, as shown inFigs. 5 and 6, against which the legs 26 and 27 abut, and are thuslimited in their inward mounting in their respective sockets.

The fiat face 29 of the joint 19 also has a fourth threaded bore 43generally centrally located therein and communicating with the interiorof the joint 19. Disposed flush against the face 29 is a generallyrectangular lampreceiving fixture box 44, one side 46 of which restsflush against the flat face 29. The box 44 is secured to the joint 19 bymeans of a bolt (Fig. 4) which passes through an aperture 48 (Fig. 2)formed in the side 46 and is threaded into the tapped bore 43 of thejoint 19. The side 46 is also provided with three apertures 49 whichregister respectively with the three tapped bores 31, 32 and 33, inorder to give access to the ,set screws 34 and 38, after the box 44 hasbeen secured in place.

Extending symmetrically from each side of the face 29, the joint 19 hasa pair of ears, 51 and 52 provided with apertures 53 and 54respectively. As will be seen in Fig. 2, the opening 48 in the side 46of the box 44, with its associated openings 49 is not centrally locatedin the side 46; therefore the box 44 extends asymmetrically out from thejoint 19.

In that portion of the side 46 extending asymmetrically out from thejoint 19, there is provided an aperture or opening 56 which registerswith the aperture 54 in the ear 52. A warning iamp 57 is disposed in thebox 44 and is provided with a reinforced nut 58 (Fig. 3) welded theretowhich receives a securing bolt 59 therein passed through the ear 52 andthe side 46 as seen in Fig. 3. The bolt 59 serves to prevent removal ofthe lamp 57 from the box 44. In order to prevent unauthorized looseningand removal of the bolt 59, the head 61 of the bolt 59 is covered by alocked cover 62, which is held in place by a lock controlled finger 63engaging in a slot in a s ecially formed washer 64 placed under the head'61. In thisway, the bolt 59 may not be unscrewed except by one havingaccess to the locked cover 62 by means of a key 66.

In order to further fortify the box 44 against unauthorized removal ofthe lamp 57, the open top of the box is provided with inwardly extendingflanges 67 which overlie the housing portion of the lamp 57 but whichstill permits the upward protrusion of the dome portion 68 of the lamp.One end of the box 44 is open but the other is closed by a strap 69welded thereacross between the side walls of the box.

Loosening of the bolt 59 by rotation of the locked cover 62 is preventedby the sockets 21 and 22 of the fitting 19.

From the above description it will be seen that the joint 19 serves themultiple purpose of securing together the lower portions of the frame11; of receiving the barricade legs 26 and 27; and of supporting thefixture box 44. It will also be seen that the joint 19 constitutes amedium by means of which the barricade may be held in assembled positionagainst unauthorized disassembly, and by means of which the box 44 andwarning lamp 57 may be secured to the barricade against unauthorizedremovalall with a single locking member 62. When the locked cover 62 isremoved, not only is access provided to remove the lamp 57, but suchremoval of the lamp 57 also gives access to the securing bolt '47, bymeans of which the box 44- may be removed if desired, and to the setscrews 34 and 38, which permit disassembly of the barricade structurefor easier transportation and storage. It will be further noted that itis not necessary to remove the box 44 in order to remove the set screws34 and 38, since they may be taken out through the apertures 49, evenwith the box 44 in place.

It will be further noted, particularly by reference to Fig. 4, that thepresence of the sheet metal sign 17 blocks access to the set screw 39,so that the horizontal shaft 13 may not be removed withoutauthorization. The sign 17 is taken out of the way simply by removingthe set 4 screws 34 and lifting the vertical shafts 12 from theirrespective sockets 21.

The configuration of the fitting 19 makes it possible to easily bolt aline of barricades together to form a long structure that may extendcontinuously across a road. This is done by removing the box 44, throughremoval of the bolt 47; and butting the face 29 of one barricade againstthe face 29 of an aligned barricade. Securing bolts may then be passedthrough one or both of the holes 53 and 54 and secured in place by nuts.Locks may be provided for these bolts and nuts if desired.

it will therefore be readily apparent that there has been provided asimple barricade structure, the key to which is a readily cast joint, soconstructed that a single lock member serves to prevent the slightestunauthorized disassembly of the barricade, yet which, when properlyauthorized, one may completely knockdown to its elemental components forready transportation and storage.

The fixture box 44 is not limited in its use to a barricade structure ofthe type illustrated in Fig. 1, but may be welded atop a single uprightvertical member '73, as shown in Fig. 7. The upright 73 is supported bya standard (not shown), and serves to hold in visible position aflashing light 57 which is locked in place by a locked bolt cover 62 asillustrated before. While the same style box as shown in Fig. 2 may beemployed for this purpose, it is preferred to omit the holes 48 and 49,and to provide the side 46 with protrusions or dimples 74, which bracketthe lock cover 62 and prevent rotation thereof, thereby guarding againstunauthorized loosening of the securing bolt 59.

While the instant invention has been shown and de scribed herein in whatis conceived to be the most practical and preferred embodiment, it isrecognized that departures may be made therefrom within the scope of theinvention which is therefore not to be limited to the details disclosedherein but is to be accorded the full scope of the claims.
